Where exactly is the solid-state capacitor?

The development of computer motherboards has been going on for a long time today, manufacturers introduced products are increasingly perfect, there are trends, the main board manufacturers intend to Os-con (solid-state capacitors) into large-scale motherboard manufacturing, such as Gigabyte 965 series with "D" type, it represents "Ultra Durable ", are used in the motherboard os-con capacitor, then what is the advantage of these capacitors, relative to the old electrolytic capacitors, the stability of the increase how much, solid-state capacitors is the main board of the stunt or quality promotion? These are the things that this article wants to bring to you.

Os-con is an organic semiconductor (organic semiconductive, short OS) aluminum electrolytic capacitor developed by Sanyo Electric Co., Ltd in 1982. Sanyo Electric Co., Ltd. has independently developed electrical conductivity of about 100 times times the organic semiconductor TNCQ mixture for electrolyte, plate is still aluminum foil. TNCQ mixture is the use of electronic conduction, so Os-con electrolytic capacitor electronic transmission speed is high, and high conductivity also conducive to temperature stability. Os-con is divided into two types, which are differentiated according to the electrolyte, one for organic semiconductors and the other for conductive polymers.

Solid capacitor at 105 ℃ high temperature, solid capacitor and liquid capacitor life expectancy is also 2000 hours, but the lower the temperature of the solid-state capacitor life will be higher than the liquid capacitor, 95 ℃, 85 ℃, 75 ℃, 65 ℃ under its life will be 1.5 times times, 2.5 times times, 4 times times and 6.25 times times. Under normal circumstances, its capacitance operating temperature should be 70 ℃ or below, so the use of all solid state capacitor motherboard capacitor life can reach an average of 150,000 hours to 20,000 hours, compared to the traditional capacitor up to 6.3 times times the maximum, to 23 life, so that the capacitor is no longer the motherboard timer bombs.

In addition, the dielectric material of the traditional capacitor is liquid electrolyte, liquid particles at high temperature is very active, the capacitor internal pressure, plus boiling point is only 120 ℃, so the traditional capacitance more prone to "slurry" situation, and some two or three-line motherboard manufacturers, due to the need to comply with the cost and the use of poor quality capacitance, so that "slurry" The odds are much higher.

Solid-State capacitance of the dielectric materials for the solid functional conductive polymers, solid particles at high temperatures, whether the particle expansion or activity is lower than the liquid electrolyte, plus the boiling point of up to 350 ℃, "high-temperature detonation paddle" the chance is very slim.

On the other hand, the solid-state capacitance in the equivalent series impedance performance, compared with the traditional capacitor has a better performance. According to capacitance test data, solid-state capacitors in high-frequency operation of the equivalent series resistance is very small, and the conductivity of the frequency is excellent, with lower resistance and more low heat output characteristics. Between the 100khz-10mhz the performance plate is obvious.

Most notably, traditional capacitors are susceptible to the use of ambient temperature and humidity, in terms of high and low temperature stability, whether-55 ℃ to 105 ℃, The ESR resistance of the solid-state capacitor is about 0.1-0.3 ohm, but the liquid capacitance will change because of the temperature, when the temperature is lower the ESR resistance is higher, even at high temperature to 105 ℃, the performance is still inferior to the solid-state capacitance.

Capacitance value, the liquid capacitor below 20 ℃, will be lower than its marked capacitance value, the lower the capacitor value is lower, under the -20℃ down about 13%, -55℃ capacitor basin up to 37%, may not be a big impact on the average user, but for the use of liquid nitrogen refrigeration as the ultimate overclocking players , solid-state capacitors can be guaranteed not due to the capacitance factor, and led to overclocking stability greatly reduced, due to solid-state capacitors in-55 ℃ when its capacitance value will only fall less than 5%.

which capacitor is more advantageous for the motherboard

Traditional electrolytic capacitors on a large scale application of dry motherboard advantage is the cost, but in a large number of solid-state capacitors, in the procurement of a certain degree of regulation chess, will make all solid-state capacitor motherboard cost to a reasonable level. The same model, such as the use of all solid-state capacitor design, ATX motherboard cost of approximately 7 U.S. dollars, M-ATX motherboard to 5 U.S. dollars.

Summarize

Os-con (solid-state capacitors) on the motherboard on a large scale application is a benefit without harm, after all, people prefer to buy products that meet the product value of the motherboard, but the use of Os-con (solid-state capacitor) capacitor motherboard is not necessarily superior quality, after all, a motherboard of good and bad, with the entire motherboard design, Production has a great relationship, the reader also cut whether the use of Os-con (solid-state capacitors) as an evaluation of the motherboard is the only basis for good or bad.
